Abstract (en)
An image forming apparatus includes a power supply unit supplied with power from outside and supplies the power to respective units of the apparatus, and a power control unit that controls the power supply unit and includes a power-supply-state storage unit that stores a power-supply-ON state or a power-supply-OFF state. The power supply unit is switchable between a first power supply mode to supply the power to all of the respective units of the apparatus, and a second power supply mode to supply the power to the power control unit. When the power supplied from outside is restarted after being shut off, the power control unit sets the power supply unit to the first power supply mode if the power-supply-state storage unit stores the power-supply-ON state, and sets the power supply unit to the second power supply mode if the power-supply-state storage unit stores the power-supply-OFF state.
